Description

Quick release structure

The invention relates to a quick release structure.

Generally speaking, a bicycle quick release device includes a shaft and a handle. The shaft is connected to the bicycle. The shaft is rotated by the handle. When the shaft is rotated to the position, the handle may be in any position. Location, including locations that may cause obstacles to riding or other dangers, not only has safety concerns, but is also less beautiful.

In this regard, there is a quick release device whose handle can slide axially relative to the shaft, and whether the handle can drive the shaft to rotate is switched by whether the tooth between the handle and the shaft is engaged or not, such as According to the patent TW M579611, when the shaft has been rotated in place but the handle is not in a good position, the handle can be slid to a position where the teeth do not mesh and then rotated. When it is rotated to the ideal position, let go The handle is meshed and positioned with the shaft again to prevent the handle from being exposed.

However, in order to ensure that the handle and the shaft have sufficient meshing power, the teeth must have a certain length to have sufficient meshing area. However, longer teeth also mean that it takes longer to stagger the teeth for rotation. The long sliding stroke makes the operation more difficult.

The main purpose of the present invention is to provide a quick release structure that can rotate the quick release handle to a position parallel to the front fork as required to avoid hindering riding.

In order to achieve the above objective, the present invention provides a quick release structure, which includes a rod, a quick release handle, a limiting member and a countermeasure.

The rod member includes a shaft member and a tooth member. The two ends of the shaft member along the axial direction are a driving end and a connecting end, respectively. The tooth member is provided at the connecting end and the outer ring surface is provided with a plurality of first teeth. The first tooth rows are arranged at intervals along the axial direction, and each of the first tooth rows has a plurality of protruding first tooth portions arranged at intervals around the axial direction.

The quick release handle includes a sleeve portion and a handle portion. The handle portion is provided on the side of the sleeve portion and extends in a direction away from the axial direction. The sleeve portion axially forms a sleeve hole, the sleeve The inner wall of the hole is provided with a plurality of second tooth rows, the second tooth rows are arranged at intervals along the axial direction, each of the second tooth rows has a plurality of protruding second tooth portions arranged at intervals around the axial direction, the The sleeve portion is sleeved on the tooth member and can slide between an engagement position and a rotation position relative to the tooth member along the axial direction. When the sleeve portion is located at the engagement position, the first tooth rows and the The second tooth rows correspond to and mesh with each other, so that the quick release handle cannot rotate relative to the rod. When the sleeve is at the rotating position, the first tooth rows and the second tooth rows are in the axial direction They are staggered and arranged alternately and sequentially without engaging with each other, so that the quick release handle can rotate relative to the rod.

One end of the limiting member is connected to the connecting end of the rod, and the other end is used to block the quick release handle to prevent the quick release handle from falling out of the rod along the axial direction.

The counteracting means is arranged between the connecting end of the rod and the sleeve part of the quick release handle so that the rod and the quick release handle tend to move away from each other and are normally located at the meshing position.

When the sleeve portion 21 is located at the engagement position, the sleeve portion 21 is pressed against the head 31 of the limiting member 30 by the force of the counterforce. It cannot continue to move along the axial direction away from the rod 10; in this embodiment, the connecting end 112 of the shaft 11 is axially provided with a screw hole 113, and one end of the limiting member 30 includes a screw section 32 The screw section 32 is screwed into the screw hole 113, and the bottom of the sleeve hole 211 is provided with a perforation 213. The inner diameter of the perforation 213 is smaller than the inner diameter of the sleeve hole 211. The perforation 213 is for the limiting member 30 to pass through. Preferably, the sleeve portion 21 of the quick release handle 20 is further away from the rod 10 with a recessed groove 214, the groove 214 is connected to the through hole 213 and the inner diameter of the groove 214 is larger than the For the inner diameter of the through hole 213, the receiving groove 214 is for the head 31 of the limiting member 30 to accommodate, and the bottom of the receiving groove 214 is for the head 31 of the limiting member 30 to abut.

In this embodiment, the limiting member 30 has a polygonal column section 33, the polygonal column section 33 is located between the screw section 32 and the head 31, the tooth member 12 axially penetrates a polygonal hole 122, The polygonal column section 33 passes through the polygonal hole 122, so that the tooth member 12 cannot rotate relative to the limiting member 30.

The counteracting means is arranged between the connecting end 112 of the rod 10 and the sleeve portion 21 of the quick release handle 20 so that the rod 10 and the quick release handle 20 tend to move away from each other and are normally located at the engaged position . In the main embodiment of the present invention, as shown in FIGS. 1 to 5, the counter-force means is a spring 40 which is elastically arranged between the end of the tooth 12 and the bottom of the sleeve hole 211. Is sleeved outside the limiting member 30; in another embodiment of the present invention, as shown in FIGS. 7 to 9, the counterforce means includes a first magnetic block 51 and a second magnetic block 52, the first magnetic The block 51 is arranged on the head 31 of the limiting member 30, the second magnetic block 52 is arranged on the sleeve portion 21, the first magnetic block 51 and the second magnetic block 52 are magnetically attracted to each other under normal conditions to make the sleeve The setting portion 21 is normally located at the meshing position; preferably, the first magnetic block 51 is provided on the end of the head 31 of the limiting member 30 facing the rod 10, and the second magnetic block 52 is annularly fixed and fixed The sleeve hole 211 is farther away from the inner wall of the rod 10.

In this embodiment, one end of the tooth member 12 that is closer to the shaft member 11 extends a flange 123 radially outward, and the one closest to the flange 123 of the first tooth rows 121 is a predetermined distance from the flange 123 When the sleeve portion 21 is at the rotating position, one of the ends of the sleeve portion 21 closer to the shaft 11 abuts against the top end 215 to the flange 123, and the second tooth row 212 is the most The one closest to the shaft 11 is located between the flange 123 and the one closest to the flange 123 of the first tooth rows 121.

In actual use, due to the force exerted by the counter-force means, the sleeve part 21 is normally maintained at the engaged position, that is to say, when the quick release handle 20 is rotated, the rod 10 will also rotate accordingly, and the drive can be achieved. The effect of rotation, and when the user applies axial force to the sleeve portion 21 to overcome the negative force, the sleeve portion 21 is moved to the rotating position, the first tooth rows 121 and the second tooth rows 121 The tooth rows 212 are staggered and do not mesh with each other, so the sleeve portion 21 can rotate relative to the tooth 12, that is, when the quick release handle 20 is rotated, the rod 10 will not rotate with it. With the above structure, In the case of not exerting force to overcome the disadvantageous means, the user can achieve the purpose of driving rotation by rotating the quick release handle 20. However, when it is rotated to the position, the handle 22 of the quick release handle 20 may be just before the bicycle 60. The forks 61 are staggered and exposed to each other, which may cause riding obstacles, or may hook objects, which may cause safety concerns, and are not beautiful. Therefore, force can be applied to the sleeve portion 21 to overcome the adverse means to make the sleeve portion 21 is moved to the rotating position. At this time, turning the quick release handle 20 will not drive the rod 10 to rotate, so the handle 22 can be rotated to a position that coincides with the front fork 61 or other appropriate positions, and then release the quick release handle 20 to make the sleeve The setting portion 21 automatically returns to the engaged position, and the quick release handle 20 is positioned on the rod 10 again, thereby ensuring that the quick release handle 20 is rotated in place and the quick release handle 20 is located at an ideal position.

It should be particularly noted that the present invention has a plurality of first tooth rows 121 and a plurality of second tooth rows 212, so it can provide better connection strength and a smaller sliding stroke. In detail, because the first tooth rows 121 And the second tooth rows 212 are arranged at an axial interval, the quick release handle 20 only needs to move the length of a row of teeth relative to the tooth 12 to make the first tooth row 121 and the second tooth row 212 completely stagger and not mesh with each other. The number of the first tooth row 121 and the second tooth row 212 are 3 respectively. Compared with a single longer tooth row with the same total length, the sliding stroke is only one-third. Therefore, the operation is easier and has enough The meshing area provides sufficient driving force.

In summary, the quick release structure provided by the present invention can position the quick release handle at any position without affecting the rotation positioning. What is important is that it can greatly reduce the sliding stroke on the premise of providing sufficient engagement driving area, and make the operation more convenient. Simple and convenient, highly progressive.
